Tolylene Diisocyanate (TDI) is the important industrial material in producing polyurethane dope. In recent years, with the development of fitment, polyurethane product was widely used. During the procedure in production and usage, TDI is dissociated from polyurethane production and will pollute indoor air. TDI is highly volatile and can irritate the skin, mucous membranes, eyes, nose and throat. The most common and most serious response occurs in the lungs. Thus, in many countries, the limit for TDI has been established and put into practice, in China the work for establishing limit for TDI in indoor air has been doing also. The character of TDI and harmfulness to human, the limit for TDI in indoor air in China and in the other countries, the measurements to control TDI pollution were reviewed in the present paper
